2023 Lexus LS 500h Review

The Lexus LS doesn't generate as much excitement as it did many years ago when it served as the brand's debut model in America. But more than 30 years later, the 2023 Lexus LS 500h continues to be the automaker's flagship sedan and a canvas for tech, comfort and safety innovations.

For 2023, the hybrid-powered 500h gets a new infotainment interface. It has a new 12.3-inch center touchscreen and finally dispenses with the clumsy touchpad control of earlier systems. (Hallelujah!) Features are now accessed through the touchscreen or voice commands. The updated voice command system can respond to natural speech and control media, navigation, climate and other functions.

Apart from the fresh features in the tech department, the LS 500h remains a posh luxury sedan that provides one of the most relaxing experiences of any car on sale. The 500h is powered by a 3.5-liter V6 hybrid, making 354 horsepower. That's underwhelming by large luxury sedan standards, but in return the 500h gets an EPA-estimated 25 mpg in combined city/highway driving. This is the best figure in the class, albeit by just a couple of mpg.

We've raved about this Lexus' sublime ride quality and noise control and appreciate its use of high-quality materials in the cabin. The LS lacks the dazzling exterior design to go with its ornate interior, which is perhaps one reason why it doesn't attract as much attention as some of its German counterparts. The Mercedes S-Class remains the segment all-star, though BMW has upped its game in a big way with the new 7 Series. There is also renewed competition from the Genesis G90. We like how Lexus updated the 2023 LS 500h's tech, but Lexus has an uphill battle on its hands among this stellar group.

The 2023 Lexus LS 500h is available in a single trim level that's powered by a 3.5-liter V6 gasoline engine enhanced with two electric motors. Combined output is 354 horsepower. A unique transmission marries a traditional four-speed automatic to a continuously variable automatic, creating a single unit. Every LS 500h includes a long and comprehensive list of standard features. The highlights include:
